Is she storing it in the door of the fridge?  Is her fridge maintaining
proper temps? She could start with a fridge thermometer,  make sure the milk
is in the back(coldest part) of the fridge.  Walk her through step by step.
Have also readin Dr. Lawrence about lipolysis making milk sour.  Apparently
some moms have a lot of lipase in their milk, it starts breaking down the
lipids and thus the sour smell.  I'm not sure, look it up, it requires some
type of heat treatment to arrest the process.
